The DSO2D15 Oscilloscope has two usb port. On the front panel there is a Type A and on the back panel there is a Type B. Is there any differential in the function between these connectors? Every jack support USB Host and USB Device?
The USB port on the front panel can be inserted into a USB flash drive to save or recall waveform files (see manual 2.9 Save/Recall for details), and the USB port on the rear panel can be used to connect to a computer for remote communication (see manual 4. Remote control for details)
